WEATHER CONDITIONS DURING 1903-'08, INCLUSIVE. 



Besides soil, fertilization, cultivation, and time of planting, 

 weather conditions, mainly the rainfall, influence the crop yield. 

 In the table presented herewith will be found the monthly and 

 annual rainfall during the years covered by the experiments, the 

 mean monthly and annual rainfall since 1868 and the same data 

 for the months of June to September, inclusive, and July to August. 



EFFECT OF TIME OF PLANTING AND RAINFALL ON YIELDS. 



In the fertilizer experiments, with the exception of the first year 

 (1904), when the planting was made early in June, the plantings 

 were made from the last of June to the middle of July. This would 

 make July and August the most important growing months for the 

 pea crop in these experiments. The larger yields in 1904 over other
